Suck some Reptile Cock.

You move quickly, working your lips and soon your mouth to the tip of his erection, and gulp it down in quick motions, sometimes pulling and back to try to work more in on your own skill. Hefting the little guy's balls in your hands to milk the extra pleasure that comes along with the action. You also start to notice the lizard taking a more active part after a few seconds of starting up, thrusting his hips up lightly into your mouth every time you reach the bottom to work with your throat to allow his full length inside. Eventually even popping through the back of your mouth into your throat, changing your sucking into a deepthroating exercise.

"F-fuck Stephan you're so good at this..." His little mewls and moans turning you on and on, him holding his hands on the desk in an attempt to not push your head down onto the base of his dick, seemingly because he knows you'll get there eventually on your own without his help. "H-here.." He squeaks out, showing you the vial of liquid you've come so used to swallowing. "L-let's see if it's still worki-ing..." An unsteady voice sounding out.

The liquid enters your mouth, you having to stop your throat game for a few seconds to fully swish it around to let it take affect fully. Of course, you continue to jack his throbbing erection in the interim, enjoying the feeling of the heavily veined flesh pump underneath your hand. Heluis's dick in the transition from one handed to two hander in terms of masterbatory habit. "Any-" You swallow him down once more mid sentence. "More of this and you'll need new underwear-" Gulk "Dude." Returning to his meat.

"I-is it bad that I'd like that?" He asks, looking at you, as if for an answer or perhaps agreement with him on the topic. Body shaking in pleasure from his newly grown in inches. "I-it'd be hot if it was even bigger, right? M-maybe something like ten inches? Y-you'd still suck me off, right?" His attempt at coxing you into agreeing with him very blatant, but you can't help but find it endearing. But, instead of pulling off to give you answer, you double down on working his shaft, the slutty glut of dick making sounds only ever produced by whorish love making rattle through the air.
